There are the yearly almanac editions that Sky & Telescope and Astronomy Magazine publish, the RASC Observer's Handbook, Guy Ottewell's Astronomical Calendar, Patrick Moore's Yearbook of Astronomy, and the expensive The Astronomical Almanac for the Year 2005: And Its Companion the Astronomical Almanac Online (Astronomical Almanac for the Year).

At least one online site, the NASA/JPL Space Calendar, covers the entire year:
